Abstract

La présente demande concerne un procédé et un appareil d'indication de motif de saut de fréquence, qui sont utilisés pour réduire une interférence entre des utilisateurs. Dans le procédé, un dispositif de réseau peut indiquer un motif de saut de fréquence à un premier dispositif terminal, et le premier dispositif terminal effectue une communication sur la base du motif de saut de fréquence, le motif de saut de fréquence étant utilisé pour indiquer une bande de fréquences qui est occupée lorsque le premier dispositif terminal effectue une communication à un moment de saut de fréquence, le premier dispositif terminal et un autre dispositif terminal ayant une collision au plus à un moment de saut de fréquence dans un cycle, et un premier cycle correspondant à au moins deux moments de saut de fréquence et au moins deux bandes de fréquences.
